EXACTLY what I was thinking. A guy has tried to blow the plane up, the masks are down, there is a hole in the side of the plane and they are sat there looking pretty calm (I haven;t got the sound on as at work so the place could be going mental but doesn't look like it)
Can honestly say that has never bothered me and I have never twigged.
However, now that you have mentioned it, I am sure it will wind me up almost as much as 'for free'
